Assertion: Two cylinders, one hollow (metal) and the other solid (wood) with the same mass and identical dimensions are simultaneously allowed to roll without slipping on an inclined plane from the same height. The solid cylinder will reach the bottom of the inclined plane first.
Reason: By the principle of conservation of energy, the total kinetic energies of both the cylinders are equal when they reach the bottom of the incline.
1. Both assertion and reason are true and reason is correct explanation of assertion.
2. Both assertion and reason are true but reason is not the correct explanation of assertion.
3. Assertion is true but reason is false.
4. Both assertion and reason are false.
